In this video we will learn what is a planetary gear set and how it works, as well as explain how to design our own planetary gearbox and 3D print it so we can see it in real life and better understand how it works. At the end of the video, we will also do some backlash and torque tests to see how well it can perform being a 3D printed gearbox.
